Keishi Pearls – A Brief History

Pearls have been a prized element for jewelry for thousands of years. Although the most expensive pearls earn their price for their regular shape, even lustre and smooth surface many “inferior” pearl shapes are now becoming popular for their unique appearance and striking style that they can add to handmade jewelry.

Pearls are produced by mollusks when a small irritant such as a grain of sand gets inside its shell. The mollusk feels this as an irritant and coats the particle with a lustrous substance known as “nacre”. Pearls tend to take on the shape of the original particle, which is why perfectly round natural pearls are so rare and valuable.

Keishi pearls are formed when the mollusk rejects the irritant before the cultivating process is completed but still produces the nacre in a freeform shape. They can also be formed alongside a cultured pearl in the mollusk. Originally cultivated by Japanese pearl harvesters in the 1920s, keishi pearls were once considered a by-product or a “mistake” since the irritant was expelled before a round pearl could be produced. But there’s no mistaking the reasons why keishi pearls have become so popular in modern jewelry making. Since they are made entirely of nacre, they have a beautiful shimmer and luster and come in a variety of naturally organic shapes, colors and sizes.

“Cornflake” Keishi Pearls

Keishi pearls are also known as “cornflake” pearls because of their irregular shapes and “poppy seed” pearls since the word “keishi” means poppy seed in Japanese. They are generally small in size but are also available in elongated shapes known as stick pearls. Their unique, asymmetrical shapes make them a favorite choice for those searching for pearl jewelry with one-of-a-kind flair and natural beauty. Once considered to be useless and common, keishi pearls are now cultivated mostly in China, Japan and the South Seas and have become a favorite among handmade jewelry designers. John S. Brana offers stunningly beautiful necklaces among his collection made from iridescent cornflake keishi pearls in varied colors, and complemented by sea glass, Swarovski crystals and fine silver.

June’s Birthstone – The Classic Pearl

June’s birthstone, the pearl, has been a favorite gemstone since the days of the Roman Empire. They are the only gemstone created by a living creature and the only one that needs no cutting or polishing to enhance its value.

Pearls are formed when an irritant enters the shell of a mollusk. The mollusk coats the irritant with a substance known as ‘nacre’, and a natural pearl is formed. Since naturally forming saltwater pearls are so rare these days natural pearls have largely complemented by cultured pearls. Cultured pearls are pearls that are formed due to a small bead or other substance placed inside of a mollusk by commercial pearl farms, which originated in Japan in the early 1900s. Today, most cultured pearls are grown and harvested around the world although most come from China, Japan, and the South Pacific. Even though natural pearls are the most highly prized, the only way to determine whether a pearl is natural or cultured is to have it x-rayed by a jeweler.

Freshwater Pearl Grading

Pearls are graded by color, luster, size and lack of flaws. Pearls that are perfectly round are quite rare, and of course, the larger the pearl, the more valuable. However, pearls of varying shapes are also highly prized. Baroque pearls are pearls that are irregularly shaped. Teardrop pearls are most often used in earrings and pendants. Coin or button pearls and smaller rice or keishi pearls are also popular choices for fashion jewelry.

While white is still the most popular color, cultured pearls are available in several other hues, such as pink, purple, blue, champagne, green and black, with black pearls rapidly gaining in popularity. As these colors are naturally occurring, it can be difficult to obtain enough of the same size and color to form one jewelry piece. White pearls are sometimes bleached and pearls may be dyed to produce new colors or to enhance their original color and luster.

Imitation pearls made from shell or glass are popular due to their affordability and similarity to natural or cultured pearls but they are lighter in weight and not as lustrous as natural or cultured pearls.

Pearl wearers should take special care with their jewelry as natural and cultured pearls can be discolored by dyes and solvents. Hairspray and perfumes should be applied before putting on pearl jewelry to avoid dulling the pearl’s creamy, lustrous surface.  By taking special care of your pearl jewelry, you will ensure a lifetime wear of  June’s Birthstone – the Pearl.
